职业性癌的调查研究,是保障职工健康,预防环境致癌的重要措施之一。1970年上海市工矿致癌因子调查研究协作组,对上海市八个主要工业系统肿瘤发病情况进行了调查,发现橡胶行业肿瘤发病率增长甚快。国外对橡胶行业肿瘤发病高虽有若干报道,但结果并不一致。为了探索其原因,协作组选择具有40余年生产历史的某橡胶厂,进行了系统的调察研究工作。在回顾调查中(1961～1970年)发现该厂恶性肿瘤发病率为3.47％,比居民高2倍,而炼胶车间更高,为5.76％,是居民的3倍。在此同时,协作组又在该厂炼胶车间三个可疑点进行现场动物暴露试验,经过两年的观察,动物
Occupational cancer research, is to protect the health of workers, prevention of environmental carcinogens one of the important measures. In 1970, Shanghai Research Institute of Industrial and Minerous Carcinogens Collaboration investigated the incidence of cancer in eight major industrial systems in Shanghai and found that the incidence of cancer in the rubber industry grew rapidly. Although there are several reports about the high incidence of oncology in rubber industry abroad, the results are not consistent. In order to explore its causes, the cooperative team chose a rubber plant with a production history of more than 40 years and conducted systematic investigation and research. In the retrospective survey (1961-1970), the incidence of malignant tumors in this factory was found to be 3.47%, which is 2 times higher than that of residents. The refineries was 5.76% higher, which is 3 times more than that of residents. At the same time, the team also conducted three live animal exposure tests at the three suspicious sites of the plant’s rubber-mixing plant. After two years of observation, the animals
